I wrote this before but I think it bears repeating.
I discovered today that a technical report can be filed by Copper Fox without an independent Qualified Person because the report is being prepared through a JV with a Producing Issuer. Teck is a Producing Issuer because they have revenues of both $30 million in the past year, and $90 million over the past three years.
Here's the clause from the 43-101 regulations:
(4) Despite subsection (1), a technical report required to be filed by an issuer
concerning a property which is or will be the subject of a joint venture with a
producing issuer is not required to be prepared by or under the supervision of an
independent qualified person, if the qualified person preparing or supervising the
preparation of the report relies on scientific and technical information prepared
by or under the supervision of a qualified person that is an employee or consultant
of the producing issuer.
